You get a forged 4.000-inch stroke crankshaft made from 4340 steel, a 58-tooth reluctor wheel for LS1 compatibility, and a set of 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts. The assembly also includes forged 4032 DSS pistons with an inverted dome design, featuring a -29cc volume and a 3.898-inch bore size, along with plasma-moly file-fit piston rings.

Eagle has put together a well-built rotating assembly using strong materials like 4340 forged steel for the crankshaft and 4032 forged aluminum for the pistons, which are known for their good thermal expansion properties, making them suitable for demanding applications. The H-beam connecting rods are a popular choice for their strength and ability to handle significant loads, further enhanced by the inclusion of ARP 8740 bolts, a trusted name in high-strength fasteners. The file-fit piston rings give you the flexibility to achieve a precise fit in your cylinders, which is crucial for optimal compression and oil control, especially when dealing with boosted or nitrous power adders. This assembly is intended for racing use, so it's built to withstand the rigors of competition.

When building a high-performance engine, a balanced and robust rotating assembly is key. This Eagle kit provides the core components needed to get your Chevy LS1 engine making serious power. Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations.
